ON CERTAIN TRUCKS EQUIPPED WITH CATERPILLAR 3126E HYDRAULICALLY CONTROLLED ELECTRONICALLY ACTUATED UNIT INJECTED DIESEL ENGINES WITH HIGH EFFICIENCY PUMPS (HEP8). THE PUMP COMPONENTS MAY EXPERIENCE A HIGH PRESSURE SEAL FAILURE WHICH CAN RESULT IN A SHORT PERIOD OF ROUGH RUNNING AND SUBSEQUENT ENGINE STALL DUE TO A LOSS OF INJECTION ACTUATION PRESSURE.

ONCE ENGINE STALL OCCURS, THE ENGINE CANNOT BE RESTARTED, INCREASING THE RISK OF A CRASH.

CATERPILLAR IS CONDUCTING THE OWNER NOTIFICATION AND REMEDY FOR THIS CAMPAIGN. DEALERS WILL INSPECT THE PUMP SERIAL NUMBERS AND REPLACE THE PUMP IF NECESSARY. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CATERPILLAR AT 1-800-447-4986, OR KENWORTH AT 425-828-5440, OR PETERBILT AT 940-591-4201.

PACCAR Incorporated (PACCAR) is recalling certain 1990-2020 Peterbilt 320 and 520 vehicles built with specific amber rear turn signals. The turn signals may also light up with the stop/tail lights when the brakes are applied. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Rear Turn signals that illuminate at the same time as the brake lights may create confusion and impair the effectiveness of the brake lights, increasing the risk of a crash.

PACCAR will notify owners, and for trucks with rear amber lights, dealers will add a jumper harness between the chassis electrical harness and amber tail lights, free of charge. The recall began August 1, 2019. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 19PBC.
